CHAMPAIGN, Ill. -- Researchers have developed new 3D-printed microlenses with adjustable refractive indices - a property that gives them highly specialized light-focusing abilities. This advancement is poised to improve imaging, computing and communications by significantly increasing the data-routing capability of computer chips and other optical systems, the researchers said.

ABERDEEN PROVING GROUND, Md. -- It's no secret the U.S. Army wants its small unmanned aerial systems to operate quietly in densely-populated regions, but tests to achieve this can be expensive, time-consuming and labor-intensive according to researchers.

A new paper in Science Advances describes for the first time how minerals come together at the molecular level to form bones and other hard tissues, like teeth and enamel.

The University of Illinois Chicago researchers who published the paper described their experiments -- which captured high-resolution, real-time images of the mineralization process in an artificial saliva model -- and their discovery of distinct pathways that support bone and teeth formation, or biomineralization.

Chestnut Hill, Mass. (12/03/2020) - Ocean pollution is widespread and getting worse, and when toxins in the oceans make landfall they imperil the health and well-being of more than 3 billion people, according to a new report by an international coalition of scientists led by Boston College's Global Observatory on Pollution on Health and the Centre Scientifique de Monaco, supported by the Prince Albert II of Monaco Foundation.

Rusted iron pipes can react with residual disinfectants in drinking water distribution systems to produce carcinogenic hexavalent chromium in drinking water, reports a study by engineers at UC Riverside.

Chromium is a metal that occurs naturally in the soil and groundwater. Trace amounts of trivalent chromium eventually appear in the drinking water and food supply and are thought to have neutral effects on health. Chromium is often added to iron to make it more resistant to corrosion.

Hypersonic flight is conventionally referred to as the ability to fly at speeds significantly faster than the speed of sound and presents an extraordinary set of technical challenges. As an example, when a space capsule re-enters Earth's atmosphere, it reaches hypersonic speeds--more than five times the speed of sound--and generates temperatures over 4,000 degrees Fahrenheit on its exterior surface.

There are around 40 million blind people in the world. Many of them would not benefit from a treatment of the eyes, e.g. in cases with damage to the optical nerve, where the connection between eye and brain is lost. For these patients, direct stimulation of the visual areas in the back of the brain could be the answer.

It's a peanut-filled world--or at least it can feel that way for kids with peanut allergies. But a new study by researchers at the University of British Columbia and BC Children's Hospital gives hope to parents and kids who face real danger from exposure to peanuts.

WEST LAFAYETTE, Ind. -- Instead of inserting a card or scanning a smartphone to make a payment, what if you could simply touch the machine with your finger?

A prototype developed by Purdue University engineers would essentially let your body act as the link between your card or smartphone and the reader or scanner, making it possible for you to transmit information just by touching a surface.

HOUSTON - (Dec. 3, 2020) - That carbon nanotubes fluoresce is no longer a surprise. Finding a second level of fluorescence is surprising and potentially useful.

How does it work? Wait for it.

The Rice University lab of Bruce Weisman, a professor of chemistry who led the pioneering discovery of nanotube fluorescence in 2002, found that single-walled nanotubes emit a delayed secondary fluorescence when triggered by a multistep process in a solution with dye molecules and dissolved oxygen.

Recently, there have been a number of electric vehicle (EV) battery fire incidents. Unlike the batteries used in small mobile devices, such as smartphones, the battery pack of an EV is composed of hundreds of battery cells, and any instability can cause major casualties and property damage. Amid various efforts to pinpoint the cause of battery fires, Korean researchers have developed a new analysis method to evaluate the thermal stability of EV batteries.

Researchers from University of Houston, Columbia University, Emory University, and University of Connecticut published a new paper in the Journal of Marketing that reviews factors that contribute to the disconnect between the data companies create and the productive use of that data.

The study, forthcoming in the the Journal of Marketing, is titled "Capturing Marketing Information to Fuel Growth" and is authored by Rex Du, Oded Netzer, David Schweidel, and Debanjan Mitra.

PARAMUS, N.J. (December 3, 2020) - Octapharma USA will present multiple clinical research posters focused on the efficacy and safety of fibryga®, Fibrinogen (Human) Lyophilized Powder for Reconstitution, for Intravenous Use in the treatment of congenital and acquired bleeding disorders during the 62nd American Society of Hematology (ASH) Annual Meeting and Exposition, a virtual medical congress to be held December 5 - 8.

Researchers at Chalmers University of Technology, Sweden, have found that graphene-based heat pipes can help solve the problems of cooling electronics and power systems used in avionics, data centres, and other power electronics.

"Heat pipes are one of the most efficient tools for this purpose, because of their high efficiency and unique ability to transfer heat over a large distance," says Johan Liu, Professor of Electronics Production, at the Department of Microtechnology and Nanoscience at Chalmers.

A new research study from the March of Dimes Prematurity Research Center led by investigators at the University of Chicago has identified new genetic markers associated with gestational length, providing new insights into potential risk factors for preterm birth.

In a collaboration between multiple labs and funded through March of Dimes, the investigators set out to map important gene regulatory regions and genetic markers relevant to preterm birth. Their first challenge was addressing the lack of functional genomics data in pregnancy-relevant tissue types.
